[4] Using block-level data from the 2000 and 2010 Census, the analysis showed that each Community District 1 neighborhood had experienced an extreme increase in its youth populations; particularly in the 0-4 and 5-9 age groups.

Similarly, between 2000 and 2010, the 5-9 age group decreased 16.4% in the entire borough of Manhattan, but increased 75% in Battery Park City, 69% in Tribeca, 44% in the Seaport/Civic Center, and 158% in the Financial District.

The study utilized a compilation of built and expected new residential units in the area and multiplied by the average household size (1.94).

Furthermore, based on the residential units tabulation, total population in Manhattan Community District 1 has steadily increased at an average rate of approximately 5% annually.

Demographic changes in Manhattan Community District 1 including the rapidly growing residential population and subsequent increase in children ages 0–18 have major implications for the area.
